System Setup and Configuration for Microsoft Windows NT Server 4.0, Enterprise Edition 1-15 Verifying Server Node Failover NOTE: When running the failover test, start with the least complex test. Do not run any client activity while testing failover events. Follow these steps to verify failover of a server node: 1. From the desktop on both server nodes, select Start, Programs, Administrative Tools (Common), Cluster Administrator. 2. When prompted for the cluster or server name, enter the name or IP address of one of the clustered virtual servers. 3. Make sure all predefined resources and groups are online. Verify that some of the resources and groups are owned by the server node you are powering down so that a failure event will result in failover of resources and groups. 4. Power down one of the server nodes. 5. Within several seconds, Cluster Administrator running on the surviving server node should bring online all of the predefined resources and groups that were previously owned by the powered-down server node. If, after a minute, nothing appears to have happened, refresh the screen by selecting Refresh (F5). Verifying Network Client Failover After you have verified that each server node is running correctly as a part of the cluster, the next step is to verify that network clients can interact with the cluster. The following steps will lead you through this validation procedure. 1. Ensure both server nodes are running, and use Cluster Administrator to verify that all groups and resources are online. 2. For each hard drive in the shared storage, Cluster Server automatically creates a cluster group that consists of a single resource, the hard drive. Using Cluster Administrator, add an IP address as another resource to one of these groups. (DO NOT use the Cluster Group.) Save the changes and return to the main Cluster Administrator screen. 3. Open a DOS window on a network client machine.

Verifying Server Node Failover
NOTE:
When running the failover test, start with the least complex test. Do not run any
client activity while testing failover events.
Follow these steps to verify failover of a server node:
1.
From the desktop on both server nodes, select Start, Programs,
Administrative Tools (Common), Cluster Administrator.
2.
When prompted for the cluster or server name, enter the name or
IP address of one of the clustered virtual servers.
3.
Make sure all predefined resources and groups are online. Verify that
some of the resources and groups are owned by the server node you are
powering down so that a failure event will result in failover of resources
and groups.
4.
Power down one of the server nodes.
5.
Within several seconds, Cluster Administrator running on the surviving
server node should bring online all of the predefined resources and
groups that were previously owned by the powered-down server node.
If, after a minute, nothing appears to have happened, refresh the screen
by selecting Refresh (
F5
).
Verifying Network Client Failover
After you have verified that each server node is running correctly as a part of
the cluster, the next step is to verify that network clients can interact with the
cluster.
The following steps will lead you through this validation procedure.
1.
Ensure both server nodes are running, and use Cluster Administrator to
verify that all groups and resources are online.
2.
For each hard drive in the shared storage, Cluster Server automatically
creates a cluster group that consists of a single resource, the hard drive.
Using Cluster Administrator, add an IP address as another resource to
one of these groups. (DO NOT use the Cluster Group.) Save the changes
and return to the main Cluster Administrator screen.
3.
Open a DOS window on a network client machine.
